I am using 2013 & 2014 for couple of months now without any problem.
All of a sudden 2013 freeze and every time I open the program it freeze
when I click something so I decided to remove and re-install it (2013
only). Now that I am experiencing sort of problem, I tried to
repair/re-install/update but with no luckL
Although I have 2014, I still prefer to have my families to be created
I would recommend making sure you have all of the latest service packs and fixes for Revit 2013 - there's an issue regarding the newer .NET. Search this forum and the Architecture forum for more info - there's a decent amount of threads about this.
